I'm old. I am not a Wordpress "Wizard" and a huge portion of the behind the curtain stuff is beyond me. That is why I like Wordpress: I do not have to know those things. It's not that I do not like change, but I prefer to edit posts the way I do now. I've looked at several "drag & drop" editors and I just do not like them.

Personally I would hope that the "Classic Editor" is with us for a very long time to come.
